COAL-SCUTTLE BOTTOM.

SPECIFICATION forming part of Letters Patent No. 738,300, dated 4September 8, 1903. Application led March 30, 1903. Serial No. 150.207. (No modelil To a/ZZ whom, it may concern:

Be it known that I, HENRY E. DETMERS, a citizen of the United States, residing' at Checotah, in the Greek Nation, Indian Territory, have'invented a new and useful Coal-Scuttle Bottom, of which the following is a specifica tion.

This invention relates to coal-seuttles and similar vessels, and has for its object to produce an improved bottom for such vessels which will eifectually resist the severe strains and concussione to which they are subjected and to reinforce the bottomV and the body of the vessel where the severest strains andfrictions occur. j

The invention consists in a bottom for coalscuttles and similar vessels,preferably slightly conveXed and having an upturned rim with an outwardly-extending bead at the juncture of the bottom and the rim, the bead and rim adapted to be expanded or sprung into the grooves formed by outwardly extending spaced encircling beads in the lower portion of the body of the scuttle or other vessel.

The invention further consists in a bottom forcoal-scuttles and similar vessels having an upturned rim and gradually decreasing in thickness from the perimeter of the bottom toward the edge of the rim and provided with an outwardly-extending encircling bead at the juncture of the bottom and rim and adapted to be expanded into grooves formed by outwardly-extending corresponding encircling beads in the body of the scuttle or other vessel.

Other novel features of the invention will appear in the annexed description and be specifically pointed out inthe claims.

In the drawings illustrative of the invention, in which corresponding parts are denoted by like designating characters, Figure 1 is avertical sectional view of a coal-scuttle with the improvement applied. Fig. 2 is a side elevation of the improved reinforcing-bottom dctached, and Fig. 3 is a plan view thereof.

In eoal-scuttles and similar vessels the greatest wear occurs upon the interior of the bottom and upon the sides near the bottom, and in most cases the Iirstfracture occurs at the point where the bottom and sides are united, and the principal object of this invention is to increase the strength ol' the bot-- tom and reinforce the above-mentioned weak point of the sides or body of the vessel by increasing the thickness of the bottom portion and providing an additional wearing-surface over the lower interior part of the sides, and in the accompanying drawings l have shown an improved form of the embodiment of the invention, the scuttle-body being represented at 1,0 of the usual shape and with the usual 4bail or handle 11 and outwardly-Haring bottom-rim 12. A

The body portion will preferablybe in one single sheet of metal with the seam at the rear, but may be otherwise constructed, if required, and this body portion is provided with outwardly-extending spaced encircling beads 13 14,-, the lower bead being preferably formed at the juncture of the flaring base-rim 12 and the body portion 10 and with the body portion between the beads preferably curved to merge into the curveof the iiaring base. In practice the space between the beads will be about two and onehalf inches for an ordinary sized scuttle but this may be changed, if preferred, as I do not wish to be limited to any specific size. The beads will be formed to project outwardly beyond the general surface `to avoid obstructions on the interior of the vessel. y

The bottom proper, 15, of the detachable bottom member of the scuttle is formed thicker than the body member and is provided with `an upturned rim 16, thinner than the bottom portion, an outwardly-extending bead 18 being formed at the juncture of the bottom and rim and adapted to be expanded into the groove formed by the outwardly-extending lower bead 14, while the upper edge of the rim is gradually decreased in thickness, as at 17, and curved outwardly to form a lip adapted to be expanded into the groove formed by the upper bead 13. The bottom 15 will preferably be slightly convexed or arched upward and provided with alternating depressions,

and projections in any fanciful shape to stiften the bottoni and increase its resisting qualities. f'

The rim 16 is curved in conformity to and closely engages the interior of the body portion between the beads 113 14, as shown in IOO Fig. 1, so that when in position the whole bottom member, including its rim, bead, and thin upper edge, closely engages the body member and requires no other fastening means.

The bottom and its rim and bead will be forced into its seat in the body member by any suitable means and will be held very tenaciously by the expanding force inherent therein, so that when once in position it will not become accidentally loosened or detached.

The reinforcing bottom member being placed to receive the impact of the coal or other material upon its thicker portion and the rim portion 16 being placed over and fully protecting the portion of the body member which receives the greatest wear it is obvious that such a scuttle will ontlast scuttles of ordinaryconstruction and all parts will be of equal strength and durability.

The combined bottom and rim will be struck up from a single piece of sheet metal and will be of ample strength to withstand the strains to which it will be subjected.

With this improvement' applied to a scuttle the upper portion may be of cheaper grade of material than ordinarily employed, while at thesame time being fully as durable as the more expensive scuttles, as the weak points are reinforced and protected, as above noted, or the life of the :more expensive scuttle will be greatly prolonged, as will be obvious, bythe addition of the improvement. Thus the cheaper grades of scuttles with the improvement applied will be fully as durable as the more expensive ones without the improvement.

It will be noted that no abrupt inward projections occur to catch the shovel or other implements employed to handle the coal or to receive the impact of the coal as it is dumped into the scuttle, which is a great advantage, and tends likewise to prolong its life. It will also benoted that the formation of the rib 13 also stiftens the body of the scuttle and renders it less liable to indentation, while at the same time the bead or rib being formed projecting outwardly offers no obstruction against which coal will strike when being thrown into the scuttle. The presence of the rib, therefore, does not produce a weak spot in the body of the scuttle, as it would if extending inwardly.

Having thus described my invention, what I claim is* v 1. A coal-scuttle consisting of a body member having spaced encircling beads near the lower edge extending outwardly beyond the general surface thereof, a bottom member having an upturned flared rim with an outwardly-projecting bead at the junction of the bottom and the rim and adapted to be sprung into the groove formed by the outwardly-extending lower bead of the body member and with the free edge of the rim gradually reduced in thickness and curving outwardly and adapted to be sprung into the groove formed by the outwardly-extending upper encircling bead of the body member.

2. A coal-scuttle consisting of a body member having spaced encircling beads near the lower edge extending outwardly beyond the general surface thereof, a bottom member having an upturned ilared rim and gradually decreasing in thickness from the perimeter of the bottom to the edge of the rim, said bottom member being provided at the junction of the ,bottom and the rim with an outwardlyprojecting bead adapted to be sprung into the groove formed by the lower encircling bead of the body member and with the free edge of the rim gradually reduced in thickness and curving outwardly to form alip to be sprung into the groove formed -by the upper encir cling bead of the body member.

3. A coal-scuttle bottom formed with an upturned iiaring rim and gradually decreasing in thickness from the perimeter of the bottom to the edge of the rim and provided with an encircling outwardlyextending bead at the juncture of the rim and the bottom and with an outturned lip at the edge of the rim.

4L. An upwardly-arched coal-scuttle bottom having an upturned rim gradually decreasing in thickness to its free edge and provided with an outwardlyextending bead at the juncture of the rim and the bottom.

In testimony that I claim the foregoing as my own l have hereto affixed my signature in the presence of two witnesses.
